摘要：

We measure the lifetime of the 8s level of Fr-210 atoms on a magneto-optically trapped sample with time-correlated single-photon counting. The 7P(1/2) state serves as the resonant intermediate level for two-step excitation of the 8s level completed with a 1.3-mu m laser. Analysis of the fluorescence decay through the 7P(3/2) level gives 53.30 +/- 0.44 ns for the 8s level lifetime.
